Abstract
Wideband guided wave magneto-optic (MO) modulation by magnetostatic surface waves (MSSW) in Yttrium Iron Garnet (YIG) - Gadolinium Gallium Garnet (GGG) has been demonstrated in a noncollinear coplanar interaction geometry. Excitation of the MSSW and efficient MO interaction at 1.152 and 1.302 μm optical wavelengths were accomplished over a wide frequency range of 3 to 7 GHz by linear electronic tuning of the dc magnetic field from 500 to 1700 Gauss. The mode conversion efficiency for 1.302 μm optical wavelength was measured to be 8.13% at 1.00 watt rf drive power. Theoretical analysis and experimental results both show that the mode conversion in this noncollinear configuration is caused by a combination of Faraday and Cotton-Mouton effects induced by the dc magnetic field and the MSSW. Such interaction configuration should result in a number of integrated optic devices for wideband communication and signal processing applications at electronically tunable microwave carrier frequencies.
